In functional phrases, the Yb:KYW crystal has located its market in high-ability laser apps resulting from its capacity to create higher energy ultrashort laser pulses when keeping a compact measurement. The interplay of its options �?seamless ytterbium substitution, sturdy absorption qualities, ultrashort pulse generation and performance in energy conversion �?positions the Yb:KYW crystal to be a cornerstone from the laser know-how, covering assorted fields ranging from scientific investigate to industrial programs.
The comparison with Eyeglasses is acceptable since the huge achieve bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
We present a dual-crystal Yb:KGW laserthat iscapable to work for a Q-switched oscillator with output ability around 24 W and pulse size of twenty ns,or as being a regenerative amplifier with output energy nearly 21 W and pulse duration below two hundred fs just after compression of chirped pulses. Both equally lasers have fantastic beam quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Display screen strong peaks at 980 nm and 1030 nm, respectively, guaranteeing economical Vitality conversion and significant overall performance in laser programs.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW as a result of very similar sizes of those chemical components around a hundred% of Yb-doping can be attained. This one of a kind attribute permits ytterbium to take the area of yttrium with nearly no disruption to your crystal’s lattice.
The monoclinic crystal constructions brings about a organic more info birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.

A large brightnessQ-switched oscillator and regenerative amplifier based on a dual-crystal Yb:KGW laser
... at 50 %-height ended up generated within a learn oscillator with selfsynchronization of the axial modes, explained within our earlier post. 21 The new version of your laser, not like that explained inside our previously short article, made use of an Yb:KYW crystal by having an N pcut (optical axis N p in the index ellipsoid was parallel to your propagation course from the laser radiation), Using the polarization on the created radiation directed together the N m axis.
Having said that, as soon as Nd3+:YAG became commercially readily available, the curiosity in CaWO4 dropped sharply. In later on yrs, specific other tungstate crystals started to draw in plenty of focus.

Li2WO4-WO3 flux was effectively applied lowering the growth temperature beneath 900 oC. As outlined by one crystal x-ray measurements, the crystal corresponds to your P2/n Place team.
